Lord of the Flies as a Religious Allegory Essay

There are numerous approaches to peruse  «Lord of the Fliesâ ». To some it is essentially an experience anecdote about a gathering of young men abandoned on a remote location, others decipher it, and consider the to be as allegories for significant parts of our regular day to day existences. A few unique speculations have been introduced, professing to clarify Golding’s imagery. What many appear to have neglected, is that the appropriate response is in that spot before them. It is in the title:  «Lord of the fliesâ », an interpretation of the greek word  «Beelzebub ». Also, what do the vast majority consider when they hear this name? The Devil, Satan himself†¦  «Lord of the Fliesâ » is a purposeful anecdote indicating the battle among Christian and Pagan qualities. The character that more than anybody speaks to Christianity in the book is Simon. The first occasion when you read through the story, he is presumably the character that is the hardest to depict an d discover a reason for. He is unique and doesn't fit in among different young men, But in the event that you go further into the book, it turns out to be increasingly more evident that Simon’s life on the island is strikingly like the life of someone else that didn't fit in. An individual that experienced somewhere in the range of 2000 years back in Israel. Much the same as Jesus Christ Simon thought about the little and helpless, he adored nature and all living. Simon is likewise a prophet. He realizes that Ralph will return to progress alive. He doesn't utter a word about himself or Piggy. Neither Simon nor Jesus are ever frightened, in light of the fact that they are sure that what is intended to happen will win. They were both ready to challenge the obscure and overcome it. Jesus prevailed upon death, Simon confronted the Beast and returned alive. Jesus did it for all the individuals living on Earth, Simon for different young men. What is so perplexing and miserable is that they were both murdered when they attempted to share what they had discovered. They were both murdered out of frustration and in the conviction that they were malevolent. On the opposite side, speaking to agnosticism and indulgence, we see Jack and his trackers. All they care about are themselves. They would prefer not to live by any standards and they don't have any regard for the island, They consume and murder without stresses, all to satisfy themselves. The clan lo ses all highlights of human progress, the main thing that impacts them, aside from their own will, is the dread of the Beast. None of them haveâ ever seen a real beast, however it is a dread of the obscure. From multiple points of view the Beast turns into a religion for the young men. As we probably am aware trackers did in old occasions, the choirbboys begin to forfeit piece of their prey, They leave meat with the goal that the Beast will like them and disregard them. The most theoretical and emblematic episode in the book happens when Simon sees this penance. The image of Christianity, and what is acceptable, meets the image of the Devil, and all that is underhanded. We realize that Simon is just fantasizing a result of his epilepsy, yet a great deal of what he sees bode well. The sow’s ridiculous head persuades him that  «Ã¢â‚¬Ëœeverything is awful business’†¦ The half closed eyes were diminish with the interminable cynisism of grown-up life.â » The Lord of the Flies says  «Fancy thinking the mammoth was something you could chase and kill†¦ I’m part of you†¦ I’m the motivation behind why it’s no go†¦ Why things are they are.â » What Golding is stating that the Devil is shrouded some place somewhere within all individuals. Without ethics, lawfulness it will in the long run surface and come out. http://www.malvik.vgs.no/engelsk/allegory.htm (1 of 2)4/20/2005 5:55:48 PM allegory http://www.malvik.vgs.no/engelsk/allegory.htm (2 of 2)4/20/2005 5:55:48 PM

But there are times that remarriage does occur. In fact, according to one study, as many as 10% to 15% of all divorced couples will reconcile.?? In those cases, the couples may have realized that the grass really wasnt greener on the divorced side. Or, maybe time did heal all wounds. Whatever the reason, remarriage between divorced couples does happen on occasion. If youre thinking of rekindling the romance with an ex-spouse, there are some critical things to consider first. Why Divorced Couples Get Remarried While the reasons for getting remarried vary from couple to couple, many people realize after the anger and frustration dissipate that they actually miss their former spouse, especially if they were married for any length of time. Then, they start to wonder what they could have done differently or if the marriage could have been salvaged. Some people even wonder if they made a mistake. Here are some other possible reasons divorced couples consider remarrying one another.?? Realize single life is unsatisfying and difficultRecognize they divorced impulsively or for stupid reasonsRealize theyre still in love with their exExperience some personal growth that led them back to the relationshipMiss the familiarity they had with their ex  Forgive and/or forget the things their ex did wrongMaintain a positive relationship with their exs family Things to Consider Before Remarrying Before you remarry your ex, you need to be sure you are both ready for the work involved because it wont be easy. And, statistically speaking, the odds are against you. For instance, second marriages often end in divorce more often than first marriages. In fact, according to Psychology Today ... a whopping 60% of remarriages fail. And they do so even more quickly; after an average of 10 years, 37% of remarriages have dissolved versus 30% of first marriages.?? If you and your ex-spouse are committed to the idea of getting back together, you need to remember these three things: The odds are against you.You must take things slowly.You should see a marriage counselor and take a marriage education course.?? Making Your Second Time Around Together Successful If you are committed to remarrying your former spouse, you should plan on being in a loving relationship for a minimum of a year before tying the knot again. During that time, you need to address the reasons why you divorced in the first place. After all, you are marrying the same person. While you both may have experienced some personal growth since the divorce, there still will be things about your ex that annoy you. Here are some suggestions to improve your chances of having a successful second marriage to one another. Get Counseling Marriage counselors agree that you must learn from your marital history or the two of you are doomed to repeat the same mistakes. Unresolved and unfinished business will resurface.?? Honestly look at what caused your divorce. If the marriage failed because of finances, be clear on how you will spend money. If problems revolved around parenting issues, work this conflict out first. If the divorce was due to infidelity, process the unfaithfulness, forgive, and rebuild trust. You also may want to read a marriage book together and take a marriage workshop  or course. The more work you do on the front end of your relationship, the better off you will be after you remarry. Building a new foundation takes time and effort. You have to confront past issues that caused conflict and learn new ways of interacting. Take a Personal Inventory When divorce happens, no one is blameless. Even if infidelity was the primary reason for the divorce, there are bound to be other issues in the marriage. And while those issues do not excuse the unfaithfulness nor can they be blamed for it, they still need to be addressed. Admit to your role and responsibility in what went wrong in your first marriage. If you cant readily do this, you will continue to struggle in this marriage. You also need to keep things completely honest between the two of you. There should be no game playing, no mind reading, and no unspoken expectations. Share with one another your hopes, dreams, and expectations. Consider Your Children Getting back together just for the sake of the kids is a bad idea. Get back together because you love (and like) one another and want to be together again.  If you do have children, dont let them know youre dating again for a while. They could get their hopes up that you will reconcile. These hopes also could put pressure on you to remarry even if things are not going as well as you would like. Be Realistic It is important to recognize that the first marriage is dead. As hard as this may be, do not let that ghost hurt your new marriage. Dont dwell on the mistakes you made in the previous marriage. Instead, focus on your future together. Also, make sure you have reasonable expectations. At the core, you will be marrying the same person. Some of the old, annoying habits will still be there. And, if you discover that things arent right, trust your gut and end the relationship.   A Word From Verywell Whatever you do, dont rush into a second marriage with your ex-spouse. Developing trust and making a marriage work requires a strong commitment by both of you. Take time to understand the dynamics of your relationship more fully before getting married again.

Smoking and the Effects on the Heart Essay - 1413 Words

The Surgeon General has called it the leading preventable cause of disease and deaths in the United States. Smoking is among the top preventable risk factors of heart disease amongst many other health problems. Coronary heart disease and strokes are the primary types of cardiovascular disease caused by smoking. They rank as the first and third leading causes of death in the United States. More than 61 million Americans suffer from some form of cardiovascular disease. Smoking increases your risk for high blood pressure, coronary heart disease, stroke, congestive heart failure, and aneurysms to name a few. More than 2,600 Americans die every day from cardiovascular diseases. To function effectively, the heart needs a constant supply†¦show more content†¦Smoking creates toxins in the blood. This greatly contributes to the development of atherosclerosis. Atherosclerosis is a condition in which fatty material is deposited along the walls of the arteries. This fatty material thickens, hardens, and can eventually block the arteries if not treated. Clots may also form around the plaque deposits. Smoking raises the levels of proteins that cause the blood to clot and also increases platelet production, making the blood stickier which further creates risk for clots. This also interferes with the blood flow and poses an added danger if they were to break off and travel through the body causeing assorted health problems such as heart attack, stroke, or gangrene. As soon as you begin to smoke, you cause immediate health risks. Within one minute of smoking, the heart rate rises significantly, as much as 30% in the first 10 minutes. Nicotine also raises blood pressure. Blood vessels constrict, forcing the heart to work harder. This makes it more difficult for the oxygenated blood to be pumped efficiently to the rest of the body. Carbon monoxide in tobacco smoke also diminishes the bloods ability to carry oxygen in the blood. It attaches itself to hemoglobin much more easily than oxygen does. Hemoglobin is what carries oxygen in the blood. Also, Smoking decreases HDL, or good cholesterol. It also increases LDL, bad cholesterol.

Taking a Look at Sports Psychology - 1561 Words

Don’t think of a pink elephant. Come on – don’t let the picture creep into your mind. Stop thinking of that†¦ Pink Elephant (Gardner). It has been proven that putting a â€Å"don’t† or a â€Å"not† into a statement can cause the brain to have difficulties in interpreting the statement. In sports, players tend to tell themselves â€Å"not† to do something. In soccer, a goalie might tell him/herself to not let the other team score a goal, and then the team does. Or in tennis, players tell themselves not to serve the ball into the net, and then they do just that. Sometimes they tell themselves to â€Å"do† something, and that athlete might end up doing the unthinkable. With three seconds left in the game, a basketball player might take the three-point shot and win the game, even though they have never been able to make that shot before. These types of scenario tend to happen all the time. Psychology, or the mental game in spo rts, is so important it can completely change the outcome of the game. Sports Psychology has become more and more influential in understanding how to play the game. Serious athletes are now training their mind just as much as they train their body. They have found that to be a champion, it now takes more than just being fit and having talent.

(2012, ch 2) the son Thomas has had to build new relationships and adapt to changes that he is not familiar and comfortable with. With the involvement of professionals Thomas was introduced to a speech and language therapist Task 1 Question 3 The focus of this essay is to describe the three parenting styles and to discuss how they might impact on children’s behaviour. The three parenting styles are authoritarian parent, an authoritative parent and a permissive parent. I am also going to describe other factors that may impact on children’s behaviour, such as changes in a child’s life, the involvement of professionals in children’s lives, the early learning stages and also the transition children experience when having to detach from their primary carer to attend day-care or school. Authoritarian parents are considered as being disciplined, strict and controlling. Rules are set and they expect their child to follow them. They will not allow the child to make any choices or decisions of their own. They use a tough disciplined technique. The rules imposed are not open to negotiation with the child. They often will not explain the reasons why the rules are being imposed and also enforce their own punishment when a rule is broken. Similar, but different to, is the authoritative parent. They are also defined as strict but they have more of an understanding approach to their child when boundaries have been broken. The parent will set boundaries, rules and guidelines that are plausible rather than enforce unrealistic ones. They will explain to the child the reasons why they are being introduced, should they broken, they will also issue non-punitive punishments. The third style is a permissive parent. They recognise their child’s developmental and emotional needs but they have difficulty imposing rules and setting boundaries. This style teaches the child that rules do not have to be followed. They are also described as being soft and too easy going. Permissive parents become a friend rather than a parent and tend to ‘give in’ to their child very easily. A child’s behaviour can be both good and bad, so parenting styles can have a positive and a negative effect on a child. Majority of children’s behaviour problems take place during times of change and transition, this is a natural progression of development. Child psychiatrist and educator Rudolph Dreikurs (1897-1972), believed â€Å"that all humans, as social beings, want to belong and be accepted by others. He identified four goals for misbehaviour: attention, power, revenge and display of inadequacy† Colloby et al. (2012, p. 62). With the focal family in Colloby et al. 2012, ch 2) the assistance of Dreikurs four goals for misbehaviour gave Cara a better understanding of both her children. Cara was able to reflect on this information, and was able to take an impartial and objective look at her children’s behaviour and address it. Initially the parenting style both Cara and Alastair were trying to establish with Thomas and Rowanna, had a disciplined approa ch, however, as they lived with Alastair’s mum Diane, she had a soft approach, and this did not help the situation as Diane would give in to their every needs, she adopted more of a permissive style. Children in this situation can get confused and frustrated not knowing which is right and which is wrong. Children require consistency as this can greatly impact on how they grow and develop. As well as the overall parenting style, family’s lives are affected by outside factors, such as changes in a child’s life can also affect behaviour. With the focal family in Colloby et al. (2012, ch 2) the son Thomas’s behaviour since being diagnosed with having a hearing impairment has had a significant effect on the family. Thomas has had to build new relationships and adapt to changes that he is not familiar and comfortable with. With the involvement of professionals Thomas was introduced to a speech and language therapist. In addition to the sessions they carry out together, Cara and Alastair play an important role carrying out further exercise and activity sessions at home. The home sessions became mundane and tedious, and Thomas was getting upset because he no longer wanted to do them. Early learning stages of a child’s life can create an impact on children’s behaviour as Swiss biologist and psychologist Jean Piaget (1896-1980) â€Å"is renowned for his four-stage model of child development that linked children’s behaviour to different stages of development† Colloby et al. (2012, p. 42). Russian psychologist, Vygotsky (1896-1934) â€Å"believed that learning occurs when a child is supported by another person to do what they could not do alone. He called this the ‘zone of proximal development’†. Colloby et al. (2012, p. 43). Whilst I agree with Piaget’s first two stages of cognitive development, the sensori-motor stage, whereby infant’s 0-2years will practice play and be allowed to explore and experience things for themselves, and the pre-operational stage, 2-7years, when a child’s play will replicate their own experiences, and they will see things from their own perspective using their own imagination, I also agree with Vygotsky’s beliefs that children can copy a person and learn from them. Some children can be further developed than others and so a child more conversant in play can assist with another child’s development. Transition in children’s lives can impact on their behaviour when a transition to daycare or school occurs. In Society today it is much more common for both parents to go out to work, Colloby et al. (2012, p47) and so the need for childcare facilities increases. Childcare professionals play an important role in the lives of the twenty-first century family for a number of reasons, Colloby et al. (2012, p. 47). An example of this could be a child possibly needing to attend day-care before they attend school so parent(s) are able to continue with their careers. By accessing the day-care placement, a child would be allocated a key person. The role of the key person is for the child to develop a bond with them so that they will make them feel safe and secure. The choice of parenting style is crucial to a child’s psychological and social development. Baumrind suggested that the majority of parents display one of three different parenting styles, Colloby et al. (2012, p. 70). The chosen style should provide a loving, supporting and disciplined approach to build a healthy and happy child. A parent’s behaviour towards a child can potentially impact significantly on his or her wellbeing. The style is generally based on how they were reared themselves, or, it can be as a result of this that they choose another. It can also be chosen as a result of the society in which they live, their ethnicity or their cultural groups.

John Deere Steel Plow Essay Example

John Deere Steel Plow Paper We chose our topic, the Cast-Steel Plow by John Deere because we all live or have lived on a farm in some period of time and found it would be interesting topic to learn more about the cast-steel plow. We thought that since we have used some type of plow we wanted to know more about it and how it was invented. We found most of our research in books like John Deere’s Company: A History of John Deere And Company and its times, also John Deere Tractors and Equipment. We have contacted John Deere’s Company in Illinois, Living History Farms in Urbandale, and Pomery Living History Farms in Washington. Also more information from Deere. com, and also facts from our American History books. How we chose our presentation category was how all three of us were more familiar with creating good boards and thought that if we could all think about our topic together so we could get a lot more information about our topic, and wanted to come up with a good idea for our board. Our project relates to the NHD theme because the steel plow was a meaningful product to farmers of the 1800s. The John Deere Steel Plow changed history forever since the land was much too rich. The Cast-Iron Plow could only go for a couple of feet and then the farmers would have to scrape off the sod. The steel plow made it easier for the farmers of the 1800s to push and also farmers could plow more acreage then a cast-iron plow. The John Deere cast-steel plow impacted the farmers back in the 1800s and it affects us now in farming. It makes everything easier, now then it has ever before.
